The biggest question might be how similar the 2014 defensive scheme will look to 2013. Yes, promoting Charles Kelly certainly offers stability, but he’s also likely to want to put his own stamp on the unit rather than offering a shot-for-shot remake of Jeremy Pruitt’s system. With some significant transition in personnel and some major losses of talent, there’s room to tinker this spring. Here’s what we’ll be watching:

Storylines: Replacing Timmy Jernigan is an impossible task, but expect plenty of hype for Lawrence-Stample this spring. He was one of Jimbo Fisher’s favorites last spring, and he’ll be counted on to step up even more this time around. The loss of Christian Jones as a hybrid rusher impacts the D line, too, and how Kelly plans to handle that role now should be interesting to watch. Edwards and Goldman are both five-star players with two years of experience under their belt, but now they’ll be looked to as leaders -- both on and off the field.

Status: B

If you want to include Jones as a defensive lineman, FSU is set to lose seven DLs to the NFL in a two-year span -- including two first-rounders in Bjoern Werner and, likely, Jernigan. That’s sapped some depth from the position, but Goldman and Edwards are as good as any D-linemen in the ACC and there’s plenty of talent behind them, too.

Storylines: Smith is the only lock for a starting job here -- and even that might depend on your definition of “lock.” But while the unit is short on experience, it’s high on talent. The battle to replace Jones in the hybrid LB/DE position should be an interesting one, with Thomas offering perhaps the most upside, but Casher and Eligwe certainly in the mix, too. Northrup is the most experienced option to replace Telvin Smith, and he’s certainly capable of blossoming into a disruptive force, but Fisher raved about Levenberry throughout 2013, and that figures to be one of the more intriguing battles of spring camp. Add Daub to the mix as an early enrollee, and Kelly’s biggest problem here might be figuring out how to get enough snaps for all his talented linebackers.

Status: B

There’s plenty of talent here, but it’s impossible to replace the veteran savvy of Smith and Jones. By year’s end, this should be a terrific group, but there’s lots to be learned this spring.

Safety

Storylines: Ramsey and Andrews were exceptional as true freshmen, but the job now is to build on that progress under a new position coach. There’s little reason to believe that won’t happen. The bigger question mark at the moment is the health of Hunter, who is recovering from a neck injury that nearly ended his career. He was the leader of the secondary last spring and summer, and his impact on a young group could be huge again in 2014.

Status: A

Terrence Brooks was always undervalued, and he’ll be missed, but Hunter, Ramsey and Andrews projects as potentially the best trio of safeties in the nation.

Storylines: Losing Lamarcus Joyner is a big blow, but there’s little to be concerned with here. Williams and Darby are both exceptional and figure to get even better in 2014. Darby was limited all season with a groin injury, so some downtime may be the priority for him. Waisome saw a ton of action in 2012 but largely disappeared in 2013. How he responds this spring might tell a lot about his future.

Status: A

It says a lot about the work Fisher, Pruitt and Mark Stoops have done over the past few years that FSU can lose a player of Joyner’s caliber and still likely have the best secondary -- and best pair of starting corners -- in the country.
